Abstract

A retrospective analysis of patients with hypertrophic obstructive cardiomyopathy treated by left ventricular myotomy and myectomy from 1972 to 1994 is reported. There were 158 patients (81 male and 77 female) with a mean age of 50.2(+/-17.2) years (range 12 to 80 years). One hundred nine patients (69%) were 60 years of age or younger, and 49 patients (31%) were older than 60 years. The overall mean follow-up period was 6.1(+/-4.8) years (range 0.1 to 19.3 years) and was 94% complete with a cumulative total of 956 patient-years. Preoperative exertional dyspnea was present in 84%, chest pain in 70%, presyncope in 54%, syncope in 31%, and cardiac arrest in 5% of patients. Preoperative cardiac catheterization was done in 150 patients, with mitral regurgitation detected in 104 patients (67%). The average maximal provocable left ventricular outflow tract gradient was 118 (+/-46) mm Hg (range 25 to 250 mm Hg). The average preoperative echocardiographic gradient at rest was 64 mm Hg, 20 mm Hg in the early postoperative period and 10 mm Hg in the late postoperative period. The mean septal thickness was 2.2 (+/-0.6) cm, 1.9 (+/-0.7) cm in the early postoperative period (p < 0.05 vs preoperative) and 1.7 (+/- 0.5) cm in the late postoper...Continue Reading
